I received this material from Reinforcement drummer Sakiman in Paramaribo 2010. The band is called Stoneblind, they played around British Guyana in the seventies and the music can be described as Rastafarian Hard Rock. On the first collection Saki plays drums, on the second he doesn't.
On YouTube a song was recently published by another Stoneblind from British Guyana. Must be related somehow... (aB)
